Magna-Power Electronics • Programmable DC Power Supplies10

XR Series: 2 kW to 10 kW

OverviewMagna-Power Electronics XR Series was designed from the ground up for high reliability and industry leading 2U (3.5” height) rack-mount power density, with output isolation for units rated up through 2000 Vdc. This product series utilizes Magna-Power Elec-tronics signature current-fed power processing, delivering robust power conversion with a high power factor—greater than 0.92 for 3Φ units. Soft-start circuitry on the input minimizes in-rush current to levels below the rated input current. High accuracy programming and monitoring levels allow confidence in power supply measure-ments, eliminating the need for external power meters.

All XR Series power supplies come standard with isolated 37-pin ex-ternal I/O, RS232, Remote Interface Software, IVI drivers for integra-tion into a variety of programming environments, and modulation capabilities for non-linear output profile emulation. Two front panel types are available for different application requirements. The stan-dard XR Version front panel (pictured in the image above) provides front panel control knobs and calibration, start and stop buttons, and a digital display for voltage and current. The C Version front panel provides a blank display panel, allowing control only from the computer or isolated 37-pin I/O connection.

Models ChartThe following chart details the available standard XR Series models. The Current Maximum (Adc) column is separated by the avail-able power levels. To determine the appropriate model, first select your output Voltage Maximum (Vdc) to find appropriate row. Next, select one desired Current Maximum from the row that contains your desired Voltage Maximum. Then, construct you model number according to the model ordering guide, above. Non-standard voltage and current configurations are available.

Model Ordering Guide

Note: Models above 2000 Vdc have high slew rate output. For models 2000 Vdc and below with the High Slew Rate Output Op-tion (+HS), ripple will be higher.
